I'm new to all the terms but it could be chatter.
Stuart
what does your cuts look like???
got any pictures...
Is it the workpiece that's vibrating a little up and down as it passes the blade? Or the saw itself vibrating? The first is more like chatter. Check the blade, tooth by tooth, any broken, chipped or out of line. Is the board twisted slightly (laying on the flat table, it rocks slightly side to side), or otherwise not straight and flat, then that could cause a problem.

Not sure what a "rail" bit is. What size is the Bosch motor? Is it variable speed?
You could be taking too big/deep of a cut. Also, the end grain should be cut first. Then, the long grain cut will take away any tear out.

Gentlemen thanks for the come back.
I'm Practicing to make raised panel shutters and sometimes I get a shutter in the wood when I cut the ends of the rails no problem with the stiles my bits are new.

not the TS...
we're talking router table here...
Have you tried to secure the wood you are cutting? I think it could work

Slow feed rate.

BTW, are you using a support to push the board past the cutter? A coping sled will help. Mine is a homemade mcgaffarin'! :grin:

I solved it I was not holding the wood tight enough and I was pushing the wood through the cutter to slow.
